Let be a finite group, a prime, a Sylow -subgroup of and a power of such that . Let denote the unique smallest normal subgroup of for which the corresponding factor group is abelian of exponent dividing . Let , , be classes of all -groups, -nilpotent groups and -supersolvable groups, respectively, be the -residual of . Let . A subgroup of a finite group is said to have -property in , if for any -chief factor , is a -number. A normal subgroup of is said to be -hypercyclically embedded in if every --chief factor of is cyclic, where is a fixed prime. In this paper, we prove that is -hypercyclically embedded in if and only if for some -subgroups of , have -property in .
